觸控感測電極結構 Touch sensing electrode structure

第1圖和第2圖是繪示根據示例性實施方式的觸控感測電極結構的示意性俯視平面圖。具體而言，第1圖和第2圖繪示了包括在觸控感測電極結構中的各個電極圖案的配置。 1 and 2 are schematic top plan views illustrating a structure of a touch sensing electrode according to an exemplary embodiment. Specifically, FIGS. 1 and 2 illustrate configurations of respective electrode patterns included in the touch sensing electrode structure.

為了便於描述，第1圖僅繪示了觸控感測電極結構的個別電極線，第2圖將電極線和連接電極一起繪示出。例如，第2圖是繪示觸控感測電極結構的感測區域I中的電極結構的俯視平面圖。 For convenience of description, FIG. 1 only shows individual electrode lines of the touch sensing electrode structure, and FIG. 2 shows the electrode lines and the connecting electrodes together. For example, FIG. 2 is a top plan view showing an electrode structure in the sensing region I of the touch sensing electrode structure.

在第1和2圖中，在同一平面上彼此交叉的兩個方向被指定為第一方向和第二方向。例如，第一方向和第二方向可以彼此垂直。箭頭所示的方向和與其相反的方向可以被認為是相同的方向。在本申請中包括的所有圖式中，方向的定義可以是相同的。 In the first and second figures, two directions crossing each other on the same plane are designated as the first direction and the second direction. For example, the first direction and the second direction may be perpendicular to each other. The direction indicated by the arrow and the direction opposite thereto can be considered to be the same direction. In all of the figures included in this application, the definition of directions may be the same.

參考第1圖，觸控感測電極結構可以包括多個電極線10。例如，每個電極線10可以在第一方向上延伸，並且多個電極線10可以沿第二方向佈置。 Referring to FIG. 1, the touch sensing electrode structure may include a plurality of electrode lines 10. For example, each of the electrode lines 10 may extend in the first direction, and the plurality of electrode lines 10 may be arranged in the second direction.

電極線10可以包括第一電極圖案13和第二電極圖案15。每個電極線10可以包括可以重複地且交替地佈置的第一電極圖案13和第二電極圖案15。第一電極圖案13和第二電極圖案15可以連續地彼此連接。 The electrode line 10 may include a first electrode pattern 13 and a second electrode pattern 15. Each of the electrode lines 10 may include a first electrode pattern 13 and a second electrode pattern 15 which may be repeatedly and alternately arranged. The first electrode pattern 13 and the second electrode pattern 15 may be continuously connected to each other.

第一電極圖案13和第二電極圖案15可以以預定角度彼此交叉。因此，電極線10可以具有包括多個折曲部分的折線(polygonal line)或鋸齒線的形狀。 The first electrode pattern 13 and the second electrode pattern 15 may cross each other at a predetermined angle. Therefore, the electrode wire 10 may have a polygonal line including a plurality of bent portions (polygonal Line) or the shape of a zigzag line.

電極線10可以分佈在整個感測區域I、中間區域III和跡線區域II(參見第6和7圖)中。 The electrode lines 10 may be distributed throughout the sensing area I, the intermediate area III, and the trace area II (see Figures 6 and 7).

參考第2圖，連接電極20可以***在相鄰的電極線10之間。在示例性實施方式中，可以通過彼此相鄰的第一電極圖案13、第二電極圖案15和連接電極20來限定凹多邊形圖案。多個凹多邊形圖案可以以鋸齒構造佈置。 Referring to FIG. 2, the connection electrode 20 may be interposed between adjacent electrode lines 10. In an exemplary embodiment, the concave polygonal pattern may be defined by the first electrode pattern 13, the second electrode pattern 15, and the connection electrode 20 adjacent to each other. The plurality of concave polygonal patterns may be arranged in a sawtooth configuration.

例如，相鄰的兩個凹多邊形圖案可以共同地共用一個邊，並且多個凹多邊形圖案可以重複佈置。因此，觸控感測電極結構可以包括包含凹多邊形圖案的網狀結構。 For example, two adjacent concave polygonal patterns may share one side in common, and a plurality of concave polygonal patterns may be repeatedly arranged. Therefore, the touch sensing electrode structure may include a mesh structure including a concave polygonal pattern.

在一些實施方式中，凹多邊形圖案可以是凹六邊形圖案。如第2圖中所示，凹多邊形六邊形圖案可以由在第一方向上相鄰的兩個連接電極20、在第二方向上相鄰的兩個第一圖案13以及在第二方向上相鄰的兩個第二圖案15限定。 In some embodiments, the concave polygonal pattern can be a concave hexagonal pattern. As shown in FIG. 2, the concave polygonal hexagon pattern may be composed of two connection electrodes 20 adjacent in the first direction, two first patterns 13 adjacent in the second direction, and in the second direction. Adjacent two second patterns 15 are defined.

凹多邊形圖案可以包括在第二方向上相對的凸部30和凹部35。在示例性實施方式中，連接電極20可以在第二方向上延伸，使得包括在相鄰凹多邊形圖案中的凸部30和凹部35可以彼此連接。 The concave polygonal pattern may include convex portions 30 and concave portions 35 that oppose in the second direction. In an exemplary embodiment, the connection electrode 20 may extend in the second direction such that the convex portion 30 and the concave portion 35 included in the adjacent concave polygonal pattern may be connected to each other.

多個連接電極20可以沿第一方向佈置以形成連接電極列，並且多個連接電極列可以沿第二方向形成。包括在相鄰的連接電極列中的連接電極20可以沿第一方向部分地重疊。 The plurality of connection electrodes 20 may be arranged in the first direction to form a connection electrode column, and the plurality of connection electrode columns may be formed in the second direction. The connection electrodes 20 included in the adjacent connection electrode columns may partially overlap in the first direction.

如上所述，通過連接電極20，凹多邊形圖案可以以鋸齒網狀結構佈置，從而可以增加在單位面積中相互連接的圖案或電極的密度，同時獲得期望的開口率。 As described above, by connecting the electrodes 20, the concave polygonal patterns can be arranged in a zigzag network structure, so that the density of patterns or electrodes connected to each other in a unit area can be increased while achieving a desired aperture ratio.

在一些實施方式中，第一電極圖案13或第二電極圖案15的傾斜角度可以在從約10°至約70°的範圍內，較佳地從約10°至約50°的範圍內。 In some embodiments, the angle of inclination of the first electrode pattern 13 or the second electrode pattern 15 may range from about 10° to about 70°, preferably from about 10° to about 50°.

傾斜角度可以定義為通過由第2圖中虛線表示的在第一方向上延伸的虛擬線和第一電極圖案13或者由虛擬線和第二電極圖案15形成的角度。在傾斜角度的範圍內，可以實現期望的圖案密度和開口率，使得包括觸控感測電極結構的觸控感測器的光學和電學性能可以改善。 The tilt angle may be defined as an angle formed by the imaginary line extending in the first direction and the first electrode pattern 13 or by the imaginary line and the second electrode pattern 15 indicated by a broken line in FIG. 2 . In the range of the tilt angle, a desired pattern density and aperture ratio can be achieved, so that the optical and electrical properties of the touch sensor including the touch sensing electrode structure can be improved.

電極線10和連接電極20可以由相同的導電材料形成。例如，電極線10和連接電極20可以包括金屬線或透明導電氧化物。 The electrode line 10 and the connection electrode 20 may be formed of the same conductive material. For example, the electrode wire 10 and the connection electrode 20 may include a metal wire or a transparent conductive oxide.

金屬線可以包括銀(Ag)、金(Au)、銅(Cu)、鋁(Al)、鉑(Pt)、鈀(Pd)、鉻(Cr)、鈦(Ti)、鎢W)、鈮(Nb)、鉭(Ta)、釩(V)、鐵(Fe)、錳(Mn)、鈷(Co)、鎳(Ni)、鋅(Zn)或其合金。這些可以單獨使用或組合使用。 The metal wires may include silver (Ag), gold (Au), copper (Cu), aluminum (Al), platinum (Pt), palladium (Pd), chromium (Cr), titanium (Ti), tungsten W), germanium ( Nb), tantalum (Ta), vanadium (V), iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), zinc (Zn) or alloys thereof. These can be used alone or in combination.

透明導電氧化物可以包括氧化銦錫(ITO)、氧化銦鋅(IZO)、氧化鋅(ZnO)、氧化銦鋅錫(IZTO)、氧化鎘錫(CTO)等。 The transparent conductive oxide may include indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium zinc tin oxide (IZTO), cadmium tin oxide (CTO), or the like.

在示例性實施方式中，電極線10和連接電極20可以由可以具有比透明導電氧化物小的電阻的金屬線形成，使得信號傳送速率可以提高並且柔性性能也可以改善。 In an exemplary embodiment, the electrode line 10 and the connection electrode 20 may be formed of a metal wire which may have a smaller resistance than the transparent conductive oxide, so that the signal transmission rate may be improved and the flexibility performance may also be improved.

觸控感測電極結構可以具有如上所述的電極佈置和構造。因此，例如，當將觸控感測電極結構用於圖像顯示裝置例如柔性顯示裝置時，可以增加單位面積中的圖案密度，同時獲得期望的開口率。因此，可以有效地防止電極或圖案被使用者看到，並且可以實現高觸控感測解析度。 The touch sensing electrode structure can have an electrode arrangement and configuration as described above. Therefore, for example, when the touch sensing electrode structure is used for an image display device such as a flexible display device, the pattern density in a unit area can be increased while obtaining a desired aperture ratio. Therefore, the electrode or pattern can be effectively prevented from being seen by the user, and high touch sensing resolution can be achieved.

第3至5圖是繪示根據一些示例性實施方式的觸控感測電極結構的示意性俯視平面圖。例如，第3至5圖繪示了跡線區域中的電極圖案佈置。 3 to 5 are schematic top plan views illustrating a touch sensing electrode structure in accordance with some exemplary embodiments. For example, Figures 3 through 5 illustrate the electrode pattern arrangement in the trace region.

參考第3圖，參考第2圖描述的電極結構可以佈置在感 測區域I中，並且多個跡線42和44可以佈置在跡線區域II中。 Referring to FIG. 3, the electrode structure described with reference to FIG. 2 can be arranged in a sense The area I is measured, and a plurality of traces 42 and 44 may be arranged in the trace area II.

跡線可以從在感測區域I中第2圖的電極結構偏離到跡線區域II。例如，第一跡線42和第二跡線44均可以具有在第一方向上延伸的折線形狀或鋸齒線形狀。第一跡線42和第二跡線44可以沿第二方向交替地且重複地佈置，以在實體上和電氣上彼此分離。 The trace can deviate from the electrode structure of Fig. 2 in the sensing region I to the trace region II. For example, both the first trace 42 and the second trace 44 may have a polygonal line shape or a zigzag line shape that extends in the first direction. The first trace 42 and the second trace 44 may be alternately and repeatedly arranged in the second direction to be physically and electrically separated from one another.

每個跡線可以包括在第1圖中繪示的電極線10。根據本發明的示例性實施方式，虛擬電極25可以設置在跡線區域II中。虛擬電極25可以設置在彼此相鄰的第一跡線42和第二跡線44之間。虛擬電極25可以包括與連接電極20相同的材料，並且可以由金屬線形成。 Each trace may include the electrode line 10 illustrated in FIG. According to an exemplary embodiment of the present invention, the dummy electrode 25 may be disposed in the trace region II. The dummy electrode 25 may be disposed between the first trace 42 and the second trace 44 adjacent to each other. The dummy electrode 25 may include the same material as the connection electrode 20, and may be formed of a metal wire.

虛擬電極25可以選擇性地連接至第一跡線42或第二跡線44中的一個。例如，如第3圖中所示，虛擬電極25可以選擇性地僅連接至第一跡線42，並且可以沿第一方向重複地佈置。 The dummy electrode 25 can be selectively connected to one of the first trace 42 or the second trace 44. For example, as shown in FIG. 3, the dummy electrode 25 may be selectively connected only to the first trace 42 and may be repeatedly arranged in the first direction.

在一個實施方式中，如第3圖中所示，虛擬電極25可以連接至包括在第一跡線42中的每個凸部30a和凹部35a。例如，虛擬電極25可以從第一跡線42在第二方向上延伸，並且多個虛擬電極25可以以鋸齒構造佈置以沿第一方向彼此部分地重疊。 In one embodiment, as shown in FIG. 3, the dummy electrode 25 may be connected to each of the convex portions 30a and the recesses 35a included in the first trace 42. For example, the dummy electrode 25 may extend from the first trace 42 in the second direction, and the plurality of dummy electrodes 25 may be arranged in a sawtooth configuration to partially overlap each other in the first direction.

虛擬電極25可以與第二跡線44在實體上和電氣上分離或隔離。除了虛擬電極25可以僅連接至一條電極線10以外，虛擬電極25可以具有與連接電極20基本相同的形狀。通過包括在跡線42和44中的第一電極圖案13、第二電極圖案15和虛擬電極25，跡線區域II中的電極佈置可以與感測區域I中的電極佈置類似。例如，在跡線區域II中可以佈置其中一些邊彼此不連接的凹多邊形圖案。 The dummy electrode 25 can be physically and electrically separated or isolated from the second trace 44. The dummy electrode 25 may have substantially the same shape as the connection electrode 20 except that the dummy electrode 25 may be connected only to one electrode line 10. The electrode arrangement in the trace region II can be similar to the electrode arrangement in the sensing region I by the first electrode pattern 13, the second electrode pattern 15, and the dummy electrode 25 included in the traces 42 and 44. For example, a concave polygonal pattern in which some of the sides are not connected to each other may be arranged in the trace area II.

在一些實施方式中，如第3圖中所示，虛擬電極25也可以設置在感測區域I和跡線區域II之間的邊界區域。因此，虛擬電極25可以用作感測區域I和跡線區域II之間的緩衝圖案。 In some embodiments, as shown in FIG. 3, the dummy electrode 25 may also be disposed at a boundary region between the sensing region I and the trace region II. Therefore, the dummy electrode 25 can be used as a buffer pattern between the sensing region I and the trace region II.

參考第4圖，虛擬電極25a可以沿第一方向交替地連接至第一跡線42和第二跡線44。 Referring to FIG. 4, the dummy electrode 25a may be alternately connected to the first trace 42 and the second trace 44 in the first direction.

例如，虛擬電極25a可以連接至第一跡線42的每個凸部30a和第二跡線44的每個凹部35a。 For example, the dummy electrode 25a may be connected to each of the convex portion 30a of the first trace 42 and each recess 35a of the second trace 44.

參考第5圖，虛擬電極25b可以設置在第一跡線42和第二跡線44之間，並且可以與第一跡線42和第二跡線44物理隔離。例如，虛擬電極25b可以具有跡線42和44之間的浮動電極形狀。因此，跡線的電學性能可以不被虛擬電極25b改變。 Referring to FIG. 5, dummy electrode 25b may be disposed between first trace 42 and second trace 44 and may be physically isolated from first trace 42 and second trace 44. For example, the dummy electrode 25b may have a floating electrode shape between the traces 42 and 44. Therefore, the electrical properties of the traces may not be changed by the dummy electrode 25b.

在一些實施方式中，佈置在感測區域I和跡線區域II之間的邊界區域處的虛擬電極25b也可具有與相鄰電極線分離的浮動電極形狀。 In some embodiments, the dummy electrode 25b disposed at the boundary region between the sensing region I and the trace region II may also have a floating electrode shape separated from the adjacent electrode lines.

如上所述，虛擬電極可以佈置在跡線區域中，使得可以在跡線區域中實現與感測區域中的圖案結構基本相同或相似的圖案結構，同時使跡線彼此絕緣。因此，可以防止由感測區域和跡線區域之間的圖案結構偏差引起的電極可視性和莫爾現象。另外，通過虛擬電極可以防止或減少跡線區域中的電極線或跡線的破裂和損壞。 As described above, the dummy electrodes may be disposed in the trace regions such that pattern structures substantially the same as or similar to the pattern structures in the sensing regions may be realized in the trace regions while insulating the traces from each other. Therefore, the visibility of the electrode and the Moire phenomenon caused by the deviation of the pattern structure between the sensing region and the trace region can be prevented. In addition, cracking and damage of the electrode lines or traces in the trace area can be prevented or reduced by the dummy electrodes.

第6圖和第7圖是繪示根據示例性實施方式的觸控感測電極結構的電極單元和跡線的配置的示意性俯視平面圖。 6 and 7 are schematic top plan views showing configurations of electrode units and traces of a touch sensing electrode structure according to an exemplary embodiment.

Shower.

基材層100可以劃分為感測區域I、中間區域III和跡線區域II。在示例性實施方式中，電極單元120可以形成在基材層100的感測區域I上，並且多個單位單元110可以一體地連接以限定電極單元120。例如，多個單位單元110可以通過合併部分115彼此連接以形成電極單元120。 The substrate layer 100 can be divided into a sensing region I, an intermediate region III, and a trace region II. In an exemplary embodiment, the electrode unit 120 may be formed on the sensing region I of the substrate layer 100, and the plurality of unit cells 110 may be integrally connected to define the electrode unit 120. For example, the plurality of unit cells 110 may be connected to each other by the merging portion 115 to form the electrode unit 120.

如參考第1和2圖所繪示的電極圖案和連接電極可以包括在各個單位單元110中。例如，可以將包括電極圖案和連接電極的網狀結構圖案化為多邊形形狀以形成單位單元110。 The electrode patterns and the connection electrodes as illustrated with reference to FIGS. 1 and 2 may be included in each unit cell 110. For example, the mesh structure including the electrode pattern and the connection electrode may be patterned into a polygonal shape to form the unit cell 110.

包括在網狀結構中的凹多邊形圖案可以以諸如鑽石形或菱形的完全凸多邊形形狀進行組裝，以限定單位單元110。多個單位單元110可以沿著第二方向佈置並且可以通過合併部分115彼此連接，使得每個電極單元120可以具有基本上凹的多邊形形狀。 The concave polygonal pattern included in the mesh structure may be assembled in a completely convex polygonal shape such as a diamond shape or a diamond shape to define the unit cell 110. The plurality of unit cells 110 may be arranged along the second direction and may be connected to each other by the merging portion 115 such that each of the electrode units 120 may have a substantially concave polygonal shape.

第6圖僅繪示一個電極單元120，然而，多個電極單元120可以佈置成以互鎖構造在實體上和電氣上彼此分離。 Fig. 6 shows only one electrode unit 120, however, the plurality of electrode units 120 may be arranged to be physically and electrically separated from each other in an interlocking configuration.

此外，如第1圖中所示的包括電極線10的跡線130可以形成在基材層100的跡線區域II上。在一些實施方式中，跡線130可以由電極線10(參見第1圖)組成，並且可以具有在第一方向上延伸的折線形狀或鋸齒線形狀。跡線130可以用作諸如觸控感測器的位置檢測線的佈線，並且多個跡線130可以組裝在焊盤區域(未繪示)中以電連接至驅動電路。包含在跡線130中的電極圖案的長度和/或傾斜角度可以與包括在電極單元120或單位單元110中的電極圖案的長度和/或傾斜角度基本相同。 Further, the trace 130 including the electrode line 10 as shown in FIG. 1 may be formed on the trace region II of the substrate layer 100. In some embodiments, the trace 130 can be composed of the electrode line 10 (see FIG. 1) and can have a polygonal line shape or a zigzag line shape extending in the first direction. The trace 130 may be used as a wiring such as a position detecting line of the touch sensor, and the plurality of traces 130 may be assembled in a pad region (not shown) to be electrically connected to the driving circuit. The length and/or the inclination angle of the electrode pattern included in the trace 130 may be substantially the same as the length and/or the inclination angle of the electrode pattern included in the electrode unit 120 or the unit cell 110.

例如，每個跡線130可以電連接至設置在感測區域I上的電極單元120中的一個電極單元。 For example, each trace 130 may be electrically connected to one of the electrode units 120 disposed on the sensing region 1.

中間區域III可以位於感測區域I和跡線區域II之間，並且可以用作兩個區域之間的緩衝區域。 The intermediate region III may be located between the sensing region I and the trace region II and may serve as a buffer region between the two regions.

在一些實施方式中，具有與合併部分115的構造基本相同或相似的構造的連接部分117可以設置在中間區域III上，並且一些電極線10(參見第1圖)可以也佈置在中間區域III上。包括在連接部分117中的至少一個凹多邊形圖案可以包括虛擬電極25。 In some embodiments, the connection portion 117 having a configuration substantially the same as or similar to the configuration of the merge portion 115 may be disposed on the intermediate portion III, and some of the electrode lines 10 (see FIG. 1) may also be disposed on the intermediate portion III . The at least one concave polygon pattern included in the connection portion 117 may include the dummy electrode 25.

例如，佈置在中間區域III上的一些電極線可以用作虛 擬線，並且其它電極線120可以用作連接至電極單元120的跡線。 For example, some electrode lines arranged on the intermediate region III can be used as a virtual The line is drawn, and the other electrode lines 120 can be used as the traces connected to the electrode unit 120.

第6圖中所示的單位單元110或電極單元120的構造或形狀提供為一個示例，並且考慮到觸控感測器設計或電路設計，可以適當地調整包括在電極單元120中的單位單元110的形狀和單位單元110的數量。 The configuration or shape of the unit cell 110 or the electrode unit 120 shown in FIG. 6 is provided as an example, and the unit cell 110 included in the electrode unit 120 can be appropriately adjusted in consideration of the touch sensor design or circuit design. The shape and number of unit cells 110.

根據如上所述的示例性實施方式，電極單元120可以包括具有基本上凸的多邊形形狀的多個單位單元115。因此，與具有簡單多邊形(例如菱形)的電極單元相比，基於觸控區域的電阻或電容偏差可以增加，從而可以改善觸控感測解析度。 According to the exemplary embodiment as described above, the electrode unit 120 may include a plurality of unit cells 115 having a substantially convex polygonal shape. Therefore, the resistance or capacitance deviation based on the touch area can be increased as compared with the electrode unit having a simple polygon (for example, a diamond shape), so that the touch sensing resolution can be improved.

基材層100可以包括可以用作形成觸控感測電極結構的基底層的膜基材。例如，基材層100可以包括觸控感測器中常用的膜材料，例如玻璃、聚合物和/或無機絕緣材料。該聚合物可以包括例如環烯烴聚合物(COP)、聚對苯二甲酸乙二醇酯(PET)、聚丙烯酸酯(PAR)、聚醚醯亞胺(PEI)、聚萘二甲酸乙二醇酯(PEN)、聚苯硫醚(PPS)、聚芳酯(聚芳酯)、聚醯亞胺(PI)、乙酸丙酸纖維素(CAP)、聚醚碸(PES)、三乙酸纖維素(TAC)、聚碳酸酯(PC)、環烯烴共聚物(COC)、聚甲基丙烯酸甲酯(PMMA)等。無機絕緣材料可以包括例如氧化矽、氮化矽、氮氧化矽、金屬氧化物等。 The substrate layer 100 may include a film substrate that can be used as a base layer for forming a touch sensing electrode structure. For example, substrate layer 100 can include film materials commonly used in touch sensors, such as glass, polymers, and/or inorganic insulating materials. The polymer may include, for example, a cyclic olefin polymer (COP), polyethylene terephthalate (PET), polyacrylate (PAR), polyether quinone imine (PEI), polyethylene naphthalate.

參考第7圖，且參考第3至5圖所繪示者，虛擬電極25可以佈置在跡線區域II上，使得可以保持跡線130之間的絕緣。虛擬電極25也可以設置在感測區域I與跡線區域II之間的邊界區域以用作緩衝圖案。從電極單元120各自延伸的跡線130可以彼此實體上和電氣上分離。例如，虛擬電極25可以設置在彼此相鄰的跡線42和44之間，以選擇性地連接至相鄰跡線中的一個。 Referring to FIG. 7, and referring to FIGS. 3 through 5, the dummy electrode 25 may be disposed on the trace region II so that insulation between the traces 130 may be maintained. The dummy electrode 25 may also be disposed at a boundary region between the sensing region I and the trace region II to serve as a buffer pattern. The traces 130 extending from each of the electrode units 120 may be physically and electrically separated from each other.

The electrode has a line width of 3 μm and an electrode thickness of 90 nm, and the lengths of the electrode patterns (the first electrode pattern and the second electrode pattern) and the connection electrode are controlled from 54.549 μm (5°) to 49.579 μm (75°) based on the tilt angle. In the range.

在第2圖中指定的傾斜角度(θ)被改變以形成實施例的觸控感測電極結構。 The tilt angle (θ) specified in Fig. 2 is changed to form the touch sensing electrode structure of the embodiment.

比較例 Comparative example

在COP基材層上形成網狀結構，其與使用APC的實施例相同以包括重複的鑽石形圖案(或菱形圖案)。電極的橫向寬度為3μm，電極厚度為90nm，各鑽石形圖案的兩條對角線的長度為59.55μm和75μm。 A network structure is formed on the COP substrate layer, which is the same as the embodiment using APC to include a repeating diamond-shaped pattern (or diamond pattern). The lateral width of the electrode was 3 μm, the thickness of the electrode was 90 nm, and the length of the two diagonal lines of each diamond-shaped pattern was 59.55 μm and 75 μm.

實驗例 Experimental example

(1)透射率的測量 (1) Measurement of transmittance

使用分光比色計(CM-3600A，Konica Minolta)以550nm的波長測量實施例和比較例的網狀結構的透射率。 The transmittance of the network structures of the examples and the comparative examples was measured at a wavelength of 550 nm using a spectrophotometer (CM-3600A, Konica Minolta).

(2)溝道電阻的測量 (2) Measurement of channel resistance

使用電阻測量裝置(87V，FLUKE)測量實施例和比較例的網狀結構的溝道電阻。 The channel resistance of the mesh structures of the examples and the comparative examples was measured using a resistance measuring device (87 V, FLUKE).

(3)可視性的評估 (3) Assessment of visibility

目視觀察實施例和比較例的網狀結構以評估電極圖案 的可視性。具體地，十個評價人員觀察網狀結構，並且通過確定在十個評價人員中清楚地看到電極圖案的評價人員數來評估電極圖案的可視性。 The mesh structures of the examples and comparative examples were visually observed to evaluate the electrode pattern Visibility. Specifically, ten evaluators observed the mesh structure, and evaluated the visibility of the electrode pattern by determining the number of evaluators who clearly saw the electrode pattern among ten evaluators.

結果顯示在下表1中。 The results are shown in Table 1 below.

參考表1，相對於具有鑽石型網狀結構的比較例，實施例的網狀結構通常表現出減小的溝道電阻和改善的可視性。在實施例的網狀結構中，電極圖案通過連接電極連接成凹多邊形形狀，從而與傳統的鑽石形網狀結構相比，使電極面積增加並且使電極可視性顯著降低。 Referring to Table 1, the mesh structure of the embodiment generally exhibits reduced channel resistance and improved visibility with respect to a comparative example having a diamond-type mesh structure. In the mesh structure of the embodiment, the electrode patterns are connected in a concave polygonal shape by the connection electrodes, so that the electrode area is increased and the visibility of the electrodes is remarkably lowered as compared with the conventional diamond-shaped mesh structure.

在具有超過70°的傾斜角度的實施例12和13中，電極圖案的密度增加並且透射率稍微降低。在傾斜角度超過50°的實施例9至13中，彎曲角度增大並且溝道電阻稍微增加。 In Examples 12 and 13 having an inclination angle exceeding 70, the density of the electrode pattern was increased and the transmittance was slightly lowered. In Examples 9 to 13 in which the inclination angle exceeded 50, the bending angle was increased and the channel resistance was slightly increased.

在具有小於10°的傾斜角度的實施例1中，與其它實施例中的電極可視性相比，電極可視性略微增加。 In Example 1 having an inclination angle of less than 10°, electrode visibility was slightly increased as compared with electrode visibility in other embodiments.

根據上述結果，在約10°至約70°、且較佳地為10°至50°的範圍內的傾斜角度內，有效地防止電極圖案被看見，同時保持較佳的透射率和溝道電阻。 According to the above results, the electrode pattern is effectively prevented from being seen in the tilt angle in the range of about 10° to about 70°, and preferably 10° to 50°, while maintaining good transmittance and channel resistance. .
